    using airborne light detection and ranging (LiDAR) data. We established two study plots in the University of Tokyo Forest in Chiba for the analysis of canopy information. We conducted a linear regression analysis between the crown lengths and widths obtained from ground surveys and those obtained from airborne LiDAR data. The crown lengths and crown widths obtained from airborne LiDAR data were correlated with those obtained from ground surveys (R2=0.46, R2=0.56). Next, we compared the crown surface areasurface areaSubject Category: Properties

    derived from airborne LiDAR data to tree growth observed in the study plot. The crown surface areas obtained from airborne LiDAR data were highly correlated with tree growth obtained from ground surveys (R2=0.95). Thus, airborne LiDAR accurately measured individual tree growth. We also compared tree growth to the proportion of crown surface area to stem surface area calculated from a stem curve based on a field survey. An exponential regression between tree growth and the proportion of crown surface area to stem surface area was carried out, resulting in a coefficient of determination of 0.74.
